Merge repos swift fm playgroung and swift bedrock library

[sebsto]

Merge the Swift-FM-Playgroung repo (this repo) with the Swift Bedrock Library.

This creates a mono repo containing both the Bedrock Library and the web playground demo app.
I iunderstand this is less than optimal as the Swift Package Manager is designed to work on individual repos.

• In the getGeneratedImage() function, the error message mentions 'completion' instead of 'generated image'; update the message to clarify that the error pertains to image generation.

throw BedrockServiceError.decodingError("Something went wrong while decoding the request body to find the completion: \(error)")
